WEST-POINT.

[With a well engraved View of that Fortress.]

THIS formidable spot of ground is on the west side of Hudson's River, sixty miles north of the city of New-York; and at this day, altho'
its former defences are many of them entirely obliterated, and the rest mouldering into ruin, exhibits marks of surprising strength.
It stood, during most of the late war, the bulwark of the confederated states, and the terror of the British arms.
It is said, that the very common soldiers of the English army, however prone to ridicule the American fortifications, never mentioned this in a ludicrous manner.

Once indeed, the idea of its subjugation was cherished; but then it was to be effected by treacher: yet, still it stood, and mocked the
wiles as well as the force of its enemies.

Explanation of the Plate

A. Constitution Island, on the east side of the river.

B. A chain, suspended on pontoons, reaching quite across Hudson's River, there about 450 yards wide.
